Available standard capacity ranges from 4GB to 512GB. Capacity, memory solution and quality test standard must be confirmed before quotation. Logo, housing color and retail or promotional packaging can be reviewed by model. For Lightning devices, Y02 and Y03 require the Y-Disk App on first use; other supported connectors are plug and play.
Are OTG USB flash drives plug and play?
Yes. All supported connectors are plug and play and require no software installation, except for the first use of a Lightning connector. A Lightning-port device must download the Y-Disk App from the App Store before first use.
Do OTG USB flash drives work with every mobile phone?
They work with mobile phones that support OTG. All mainstream smartphones released since 2015 generally include OTG functionality, but buyers should still confirm the target phone model, connector and operating system before placing a bulk order.
Which OTG USB flash drive sells best?
The basic Type-C model serves mainstream everyday demand, offers strong value for money and has the highest sales volume in this range.
Why do USB flash drive prices change so quickly?
The memory chip accounts for more than 90% of the USB flash drive cost, so changes in chip prices directly affect the final product price. Since 2025, large-capacity and high-speed memory chips have also been widely used for AI-related demand, reducing the supply available for ordinary electronic products and increasing USB flash drive price volatility.
What warranty do you provide?
TOPTAI provides a one-year warranty. If a quality problem occurs within one year, TOPTAI will arrange repair or replacement and cover one-way shipping.
How should I choose OTG USB flash drives for wholesale?
Start with the ports used by your customers. Choose TT180, TT192 or TT193 for USB-C and USB-A users. Choose Y02 for Lightning, Micro-USB and USB-A users, or Y03 when one model must cover Lightning, USB-C, Micro-USB and USB-A. Then select capacity, housing, packaging and price tier.
Which OTG USB flash drive is best for broad device compatibility?
Y03 provides the broadest connector mix with Lightning, USB Type-C, Micro-USB and USB-A. Y02 covers three legacy-oriented connectors, while the TT180, TT192 and TT193 models focus on current USB-C devices and USB-A computers.
What capacities are available?
Standard capacity ranges from 4GB to 512GB. Confirm the memory solution, real usable capacity, packaging and testing requirements before quotation.
Is a genuine 1TB USB flash drive available?
Yes, but genuine 1TB storage chips are expensive. Even a two-chip solution using two 512GB chips generally costs more than USD 40, while a single high-speed 1TB chip commonly costs more than USD 90. Offers below normal hardware cost should be verified carefully.
How can buyers check the real capacity?
Use H2testw to write and verify the full drive. It helps confirm whether the reported capacity matches the usable physical storage.
Can these products be customized?
Logo, housing color and retail or promotional packaging can be reviewed by model. Final MOQ, price and lead time depend on capacity, artwork, packaging and quantity.
What are the MOQ and sample times?
TT180, Y02 and Y03 list an MOQ of 200 pcs. TT192 and TT193 list an MOQ of 500 pcs. The listed sample time is 3 days; confirm capacity, stock and customization before ordering.
